T 0 alllwkom it may concern Be it known that I, THOMAS A. Dr: Vrnnrss, a citizen of the United States, and a resident of Toledo, in the county of Lucas and 5 State of Ohio, have invented a certain new and useful Atomizer or the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of refer this specification.

This invention relates particularly to valves for 'atomizers and similar instruments, but is not restricted to such use as it may be used in any connection for which it may be adapted or appropriate.

The primary object of my invention is the provision, in an instrument of this character,

. of improved means for carrying the spray -parts to permit an axial turning thereof to facilitate the directing of a spray in dif ferent'directions, and which is also operable to close the communication between the interior of an associated liquid receptacle, the spraying parts and the atmosphere, whereby to facilitate a packing of such instruments in traveling cases or the like Without removing the liquid contents of the instruments and without danger of leakage of such contents to the injury of articles packed there with. c

The invention is fully described in the following specifica' on, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the acompanying 40 drawings. in which,- 7

Figure l is a. side elevation of an instrument embodying my invention with :the spraying parts adjusted relative to the can rying head for lateral horizontal spraying.

Fig. 2 is a cross-section of the invention on the line 1r, :1: in Fig. 4 with parts broken away. Fig. 3 is a side elevation of the movable valve member with the attached tubes broken away. Fig. 4 is a central longitudinal vertical section of the carrying head and associated parts with the valve in open position, and'Fig. is an elevation of the valve plug turning collar mounted on the valve plug with the securing nut removed.

Referring to the drawings, 1 designates or neck thereof.

once marked thereon, which form a part of the liquid receptacle of an atomizer or similar instrument, and 2 a head for closing the neck of the receptacle, as by threading into a ferrule or sleeve 3 secured to the open top The head 2 is provided #80 horizontally thereihrmigh, or in transverse relation to the receptacle neck, with a preferably tapered or slightly conical passage or opening at into which a valve plug 5 of com plemental tapered or conical form is mount as ed for rotary adjusting movcments therein. Two tubes 6 and 7, which for convenience may be designated the air and liquid tubes, respectively, of the instrument. project longitudinally from the larger end of the valve plug 5 and terminate at their outer ends in a common spray head 8, which. in the pres ent instance, is pivotally carried by the tubes to permit an adjustment thereof relative to the tubes to facilitate a discharging of liquid in spray form in a direction longitudinally of said tubes or transversely thereof.

It is to be understood that the invention is not restricted to the use of any particular form of nozzle but contemplates broadly the use of any type of nozzle adapted for a lateral discharge of spray or fluid over the tubes 6 and 7. A passage 9 is provided longitudinally through the valve plug from one end to the other thorcoi with one end opening into the inner end of the tube 6 and with its other end opening without the small end of the valve plug axially thereof to adapt it to have communication with a source of fluid, such for instance, as air 80 under pressure. The liquid tube 7 has the inner end of its bore opening into a passage 10 in the valve plug, such passage extending rcarwardly therein from the tube 7 to adjacent the center of (he head Qund is thence forked to form the two laterally extending branches l0 and 10*. which open without the side of the valve plug in position for one or the other thereof to register with the 7 liquid supplypassagc 11 in the lower porlion of the head 2 when the valve is intwo different positions of its rotary adjustment. The outer ends of the branch pasage 10 and 10 are disposed one-quartor of a turn apart, in the present instance, so that one will register with the sup-ply passage 11 when the plug 5 is turned in position to place the tubes 6 and T in horizontally spaced relation, and the other will register with the supply passage when the plug is A small nee le-prick opening l3 extends laterally fromthe fluid passage 9 of the plug into communication with a sag-v valve menta core 14 extending circumferem tiallyo the plug. The groove 14 has com munication with 'the atmosphere through a vent channel 15 in the upper portionof the head 2, the lower end of such channel being in register with the groove and has communication with the interior of the receptacle through a channel 16 in the lower portion of the head 2 when either of the branch passages 10* or 10"v is in register with the supply passage 11. The groove 14 terminates at one end adjacent. to the channel 16 so that when the valve plug is-turned in counter-clockwise direction (referring to Fig.1) the groove moves out of register with the channel 16, thereby closing the I communication between the interior of the that when either of the passages 10 or 10 1 restricted communication between the pasis in register with the liquid supply passage 11 in the head the interior of the receptacle will be in communication with the atmosphere through the restricted channels 15 and 16 and connecting groove 14, thus preventing a vacuum from occurring in the receptacle upon the discharge of liquid therefrom. Air under pressure is also supplied to the. interior of the receptacle when the instrument is being operated due to the restricted communication 13 between the passage 9 andgroove 14. The purpose of the sage 9 and the interior of the receptacle is to permit a flooding of the spray parts ofthe instrumcntwvhen air pressure is present in the passage 9 and the channel 15 is closed. as by placing a thumb thereover, thus causing a portion of the air which is being forced through the passage 9 to pass therefrom into the interior of the receptacle to cause an air pressure upon the top of the fluid within th receptacle.

The valve plug 5 is provided at its small end with a neck or reduced portion 17 which proje cts beyond the head 2 when the plug is seated therein and terminates in'threads A collaiultl, which preferably has a knurled edge to facilitate. a hand turning thereof, is placed over the extension 17 with .its inner end or side abutting against the head 2 and isprevented from turning relative to the extension 17 by having coacting portions thereof flattenccL-as shown at 20 in Fig. 5, or engaging in any other suitable. manner. A. nut 21 is secured onto the threaded end portion 18 of the extension 17- and serves to hold the collar 19 in position on such extension, and in addition forms a continuation of the passage 9-and a heel piece for the attaching of an air ressure relative to the head 2 are limited, in the' present instance, to a halt turn due to a stop pin 24.- p'rojecting laterally from the large end portion of-the valve plug into a recess 25 in the adjacent side of the head, such recess being of suitable length for such purpose.

It is cvidentin the use of my improved valve that when the same isv turned to the v right from the position noted in Figs. 2 and 4 both of the passages 10 and 10 will be out of register with the sup ly passage 11 and-the channel 15-16 will he closed to the'groove 14 thuspreventing an escape or liquid from the receptacle should it be inverted or placed on .its side. When the passage 10 is in communication with the liquid supply passage 11 the spraying parts are in position for directing a spray in a horizontal or transverse direction relative to the receptacle, and when thepassage 10 is in com.- munication with said supply passage the spray parts are in position for directing a spray either upwardly or forwardly relative to the instrument.

Having thus described my invention, what I claim as new, anddesire to secure by LettersPatent, is,-
